3.3 AC Side(AC IN and MOTOR) Electrical Connection
Step1: Please connect the AC wire according to the following steps:
Operation Instruction
Operation Demonstration
1. Step Using wire crimpers, connecting
AC cable and Cold-pressed
Terminal(SC4-5).
Step2:
JNP550L-V5、JNP750L-V5、JNP1K1L-V5、JNP1K5L-V5、JNP2K2L-SE-V5:
The AC conductor (R, S, PE, U, V, W) is fixed on the terminal through the
corresponding waterproof terminal on the terminal cover. Notice: R is connected to the
fire line, S is connected to the zero line, and PE is grounded. R, S and PE pass through
the AC IN waterproof terminal, and U, V and W pass through the MOTOR waterproof
terminal.
JNP2K2L-V5、JNP3KL-V5、JNP3K7L-V5、JNP4KL-V5:
Fix the AC input cable through the AC IN waterproof connector to the corresponding
terminal (R, T, PE), and fix the water pump power supply cable through the Motor
